Hi Alane!The beauty of this recipe is that you can do everything in one pan on the stove top. Maybe we should exchange the word roast with toast in the pan. After you are done boiling your potatoes on the stovetop in a pan. Just remove the lid and finish the cooking procedure right on the stove top at a medium heat with the lid off. Just until they are little toasty and the tomatoes just start to soften. If you prefer, you can put the potatoes and the tomatoes in the oven at 375 degrees F for about 10 minutes or just until the tomatoes start to soften. Wishing you a super weekend ahead.
